Nov. 10, 1936. LHUFFMAN MANIFOLDING UNIT Filed Jan. 11, 1935 Patented Nov. 10, 1936 UNITED STATES PATENT OFFICE MANIFOLDING UNIT Application January 11, 1933, Serial No. 651,099

8 Claims.

This invention relates to improvements in man.- ifolding forms wherein clean record leaves are so arranged with respect to a transfer leaf or leaves in each rnanifolding unit of the form that the forni may be manipulated to inscribe a writing f on the record leaves of the unit, to detach the removable record and transfer leaves following use and to prepare the succeeding unit for an inscription, without soiling the hands of the operator or soiling any material or object with 1,9 which the form might come into contact.

The invention is adaptable to manifolding forms whatever may be the number of record copies produced by each unit and whatever may be the relative arrangement or connection of the 1.5 several units which make up the form, whether books, cut forms, fanfolds, or the like.

I attain the object of my invention by providing record leaves and a transfer leaf or leaves so constructed and associated together in each unit of the form that all the manipulations required to work the form may be accomplished without contact with or expOSure of a transfer surface of the transfer leaf or leaves.

In a duplicate form a preferred arrangement Il consists inY the provision of clean surfaced original and duplicate record leaves connected together by an intervening transfer leaf having transfer material on the side adjacent to the duplicate record leaf only, the relative arrangement being such that the transfer coated surface of the transfer leaf is not exposed to contact outside of the form during manipulation thereof.

In a triplicate form a single transfer leaf, @cated with transfer material on both sides, may be Used, and the connection between the original record leaf and the triplicate record leaf may be through a translucent record leaf normally overlying one transfer surface of vthe transfer leaf, the arrangement being such that the several manipulations required to work the form may be accomplished without contact with or exposure of either transfer surface of the transfer leaf.

1f the arrangement is in the form of a duplicate book the original record leaf may be remo-ved *5 .following use .and the. transfer leaf and duplicate record leaf thrown back to expose the succeeding unit without Contact with 0r exposure 0f the transfer surface of the transfer leaf and the transfer leaf may then be detached, or it may be detached later at the leisure of the operator to- 4gether with a number of other used transfer leaves, Without contact being made with or exposure of its transfer surface.

M AVI f the arrangement is in the form Q a triplicate book or in any other fashiomthe same desirable objects may be accomplished, due to the particular construction and arrangement as hereinafter more specifically set forth.

The invention is hereinafter more specifically described and is illustrated in the accompanying drawing in which Fig. 1 is a perspective View of a single mani-- folding unit including two record leaves;

Fig. 2 a perspective View of a hook made up of a plurality of units such as lshown in Fig. 1; and

Figs. 3 to 5 perspective views of modifications of the invention.

In the drawing like numerals of reference indicate corresponding parts in the different figures.

In the simplest form a unit comprises three connected leaves I, 2 and 3 folded in zigzag form. Leaf l forms an original record, leaf 2 is a transf fer leaf carbonized on its under side and leaf three is a duplicate record to which entries on the original are transferred by the leaf 2. The leaf 3 is shown as provided With a stub 4 delimited by the line of Weakness 5. (See Fig. l.)

If the units are to be used as what are known as cut forms the stubs 4 may be punched in order that they may be filed on post binders.

To form a book a suitable number of the forms will be bound to a cover of ordinary construction as shown in Fig. 2. This cover comprises the back 6, top cover leaf 1 and stop leaf 8, having the usual functions.

When a unit is used in a book or in sets of out forms the bottom of each original record leaf I will be the end remote from the stub.

The method of using the unit Will be obvious, 35 Whether as a cut form, fanfold or in a book. Any entry made on the original record leaf is transferred to the duplicate record leaf by the transfer leaf. After the original has been torn off, the transfer leaf remains attached to the dupli- 40 cate leaf with its transfer surface hidden. If the unit is being used in a book the leaves 2 and 3 are then grasped at their joined ends and thrown back against the front cover to expose the original of the next unit which is ready fo-r use as soon as the stop leaf 8 has been repositioned under the new top unit.

In these operations no carbonized surface is n contacted by the hands. The transfer leaf may be left attached to the duplicate or may be removed at any time.

The three leaves may be formed of an integral sheet of paper but, as it is usual to make the transfer leaf of a special thin paper, it will generally be preferable to use separate leaves adhesively secured together.

For this purpose and for cleanliness in handling the transfer leaf will usually be formed with uncarbonized margins both back and front at each end.

To facilitate separation of the original from the duplicate a line of weakness il is provided in the original below the part of its end adhered or otherwise connected to the transfer sheet 2. In tearing off the original record leaf, the attached ends will be grasped by the fingers of one hand and the leaf torn off with the other. The under margin of the transfer leaf being clean the fingers grasping it are not soiled.

To facilitate the separation of the duplicate from the transfer leaf a line of weakness I2 is provided in the underlying duplicate above the part of its end attached to the transfer leaf. In separating the transfer leaf from the record leaf the attached margins of the record leaf and transfer leaf are grasped with one hand while the underlying record leaf is held down, adjacent the stub, by the other hand, when a tearing movement will separate the record leaf on the line of weakness leaving its margin attached to the transfer leaf.

The transfer leaf thus has attached to it the upper margin of the original leaf and the lower margin of the duplicate, leaving both record leaves free of attached fragments.

A triplicate book embodying my invention is readily made by the addition of one leaf.

It is possible, of course, to make three of the leaves from a single sheet of paper, but usually it will be preferable to use separate leaves adhesively secured together as thus the preferred quality of paper may be used for each type of leaf.

In Fig. 3 I show a triplicate book in which the original leaf I is connected with the upper end of the double sided transfer leaf 2, which is attached with the translucent leaf 9 to the lower end of the leaf 3. The transfer leaf forms the hinge connecting the two record leaves. This transfer leaf 2 is carbonized on both sides and transfers to the upper surface of the record leaf 3 and to the underside of the translucent leaf 9. In this form the original record leaf is provided with a line of weakness i8 along which it may be separated from the transfer leaf 2, which transfer leaf may remain with the record leaf 3. When this unit is used in the book and the transfer leaf 2 is permitted to remain with the record leaf 3 the two leaves 2 and 3 will be readily thrown back together as in the handling of the duplicate book illustrated in Figs. 1 and 2. To the above extent the construction of Fig. 3 is similar to the construction shown in Figs. 4 and 5. Figs. 4 and 5 are variants of Fig. 3, however, as hereinafter described.

In Fig. 4 a further variant is shown, the leaves l, 9 and 2 being connected at their upper ends, while the leaf 2 is connected at its lower end to the lower end of the leaf 3.

In Fig. 5 a variant is shown in which the upper ends of the leaves l and 2 are connected and the lower ends of the leaves 2 and 3, while the leaf 9 has its lower end connected to the lower end of the leaf l.

In all forms the several manipulations required to work the form may be effected without contact with or exposure of either transfer surface of the transfer leaf.

While I have shown preferred embodiments of my invention numerous modifications are possible which would fall within the scope of my invention.

What I claim as my invention is:
